The object-oriented multi-domain language Modelica has been applied very successfully in some prominent Aerospace projects such as POA or MOET und proved to be an ade­quate tool to describe heterogeneous en­ergy systems consisting of electrical, elec­tronic, hydraulic, pneumatic, thermo-dy­namical and mechanical components.

Regarding the DLR project “Next Generation Train” the department of System Dynamics and Control cooperates with the DLR Insti­tute of Vehicle Concepts in the NGT work package Energy-Management providing methods and tools support in particular regarding high level analysis methods like optimisation, anti-optimisation, uncertainty-modelling and Monte-Carlo-Simulation.

In May 2008, the FP7 project Sympass, in which the institute took the lead for the work-package System Simulation Platform, was approved by the EU commission and started. The project was supposed to develop a simulation environment for the complex auxiliary power system in railway vehicles together with its onboard control system called TCMS. The environment should be open to hardware-in-the-loop and software-in-loop applications, see figure below.
